What's New / NOTES
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

NOTE: Some of the data on this page has not been verified and should be used with that in mind. It may and occasionally will, be wrong. The tide reports are by xtide and are NOT FOR NAVIGATION.

Pattern synopsis forecast: short-wave impulse and associated upper
divergence bullseye is now sliding across northern michigan with
a broad area of light snowfall working through the eastern half of
the cwa. Attending surface low is over the tip of the mitt ne
lower michigan with a wavy front through the m-68 corridor and
arcing back down through lake michigan. Some very cold although
very dry air is poised north of the front across ontario which
will overspread the region overnight into Tuesday.

Meanwhile, along the arctic front, better lake enhancement has
finally materialized and is now wrapping back down through emmet,
cheboygan and charlevoix counties, some of the best snows of the
day. Also of note, a nice mesoscale low has formed over northern
lake michigan within the sharp low level trough and is now making
it's way onshore into the grand traverse bay region... Likely
aiding the enhancement.

Short-wave and attending surface low will advance out of northern
lower michigan over the next several hours while attending cold
front gets pulled down through northern lower michigan by early-
mid evening. We may yet get a final push of transient heavier
snowfall that drops down through northern lower mi with the front
bringing some "last minute" accumulating snow.

For the advisory area itself, I was all set to cancel it ahead of
schedule given the lackluster snow accumulations thus far. But as
mentioned some of the best enhancement of the day is now ongoing,
and just in time for the beginning of the afternoon commute. So
i'll probably just let it ride until the heavier snows drop down
on through.

Quick transition to northerly flow lake snow showers takes shape
this evening with colder but much drier air overspreading the
region through the night. There will be a window of time through
this evening where better larger scale moisture weak or neutral
qg-forcing for ascent will lead to some decent lake effect snow
showers in and around the grand traverse bay region before
diminishing overnight as strong subsidence and much drier air work
into the region. With that in mind, I have beefed up snow
accumulations a bit in and around the grand traverse bay region.

Pattern synopsis forecast: broad troughing continues aloft across
the great lakes through the middle of the week before heights begin
to rise thanksgiving day. Weak surface ridging overhead during the
day Tuesday will quickly get ushered by a developing clipper system
set to drop southeast across the northern great lakes Tuesday night.

A strong area of canadian high pressure will then settle atop the
region by Wednesday afternoon through the end of the forecast period
on Thursday.

This will shift any lingering light snow showers to the typical west
flow lake belts near the m-32 corridor, although any accumulation
through the day is expected to be minimal. Deeper moisture begins to
arrive from the northwest by early evening in advance of an
approaching clipper system, set to trek from northern lake superior
Tuesday evening to eastern lake huron by Wednesday morning. Lake

enhanced snowfall will be the primary concern with this system given
a sufficient delta t environment, although a cold front crossing the
region will certainly bring synoptic support with it as well. As was
alluded to be the prior forecaster, lake aggregate troughing off of
superior is expected to result in a more impressive area of low-
level convergence across portions of eastern upper than along the
northwest lower shoreline. Model forecast soundings suggest initial
inversion heights in the 9-10 kft range gradually fall throughout
Tuesday night, along with moisture stripping away to the east behind
the departing wave aloft. Expected snow accumulation from this event
across eastern upper and northwest lower continue to look on the
order of 1-3 inches, highest across the tip of the mitt... Lesser
amounts under an inch east of i-75 south of m-32.

Strong cold air advection behind the departing system during the day
Wednesday will likely be sufficient enough to continue light
northerly flow lake effect snow showers; however, minimal
accumulation and associated impacts are expected at this time.

During the day Thursday, warm air advection will gradually take over
aiding to gradually boost temperatures aloft and putting an end to
any lingering light lake induced snow showers flurries.

Temperatures remaining below normal through the forecast period with
highs ranging from the low-upper 20s across the forecast
area... Coldest on Wednesday as many areas struggle to reach the mid
20s. Overnight lows certainly chilly as well with the coldest temps
expected Wednesday night... Ranging from single digits across many
areas to the mid-teens nearest the great lakes shorelines.

Brief mid-level ridging will drift overhead giving a boost to
temperatures late this week. However, troughing redeveloping
upstream will aid in bringing another system across the region
Friday night into Saturday. Given the moderating thermal profile
through this time, rain looks to be the predominant precip-type
before cooler temperatures and more snow chances return for the
following week.

Low pressure is departing across lake huron. Last vestiges of snow
and mixed precip will move southward across the area this evening.

Developing northerly winds will bring chilly but dry air
southward, resulting in only light lake effect snow showers
overnight and otherwise improving vsbys cigs. Low-endVFR
conditions should persist for most of Tuesday.

Northerly winds will be gusty at times tonight, then become
lighter while backing toward the west Tuesday.

Issued at 330 pm est Mon nov 19 2018
behind departing low pressure, gustier northerly winds develop
tonight leading to small craft advisory conditions on lake
michigan and huron. Winds will decrease late tonight through a
good part of Tuesday. But, stronger winds arrive once again later
Tuesday afternoon and into Wednesday. Expect marine headlines to
continue.
